Add menu option to skip lk2nd_boot

This can be useful when dual-booting Android on the internal storage and postmarketOS on an SD card without physically removing it or using fastboot boot with the flashed Android boot image. This can be useful considering Android is required to charge the battery (safely) for some devices.

The reboot option already boots to Android.

The reboot option already boots to Android.

It doesn’t seem to for me. It goes back to lk2nd and if I do nothing, boots what’s on the SD card.

Understood. I've not flahsed lk2nd in one device and it reboots to Android.

Hi! First of all, sorry for the delayed response.

Generally, I prefer to minimize the amount of user-visible logic in lk2nd's boot flow, as it increases the space for confusion and possible edge cases. Would it be possible to implement your usecase (i.e. dual-boot linux and android) by installing lk2nd into a recovery partition and using the key combo to boot to lk2nd+linux on sdcard vs booting to android without any key combo?

Hi.
I suppose it could work, though it would mean that there is no recovery available, which could theoretically be used by Android to install OTA updates.
Another issue is that Android seems to replace the recovery image on boot (TWRP has an option to patch this system out of the ROM when started).
